Zero-Knowledge Circuit Engineer

role overview

We are looking for a zero-knowledge circuit engineer to help build and optimize our implementation of the EVM within a zero-knowledge circuit (the zkEVM). You will work alongside the applied ZKP team from the Ethereum Foundation to develop open source code to provide succinct validity proofs for EVM execution. This is a critical piece of our mission to build a fully EVM-compatible zkRollup.

Your day-to-day work will involve writing and testing pieces of the zkEVM system, contributing to our Rust-based development tooling, and optimizing the zkEVM circuits for performance. We are looking for someone with either prior experience developing ZKP circuits or extremely strong problem-solving / engineering fundamentals to ramp up quickly in this cutting-edge domain. The ideal candidate will be able to contribute correct circuit code while working in a rapidly evolving open source ecosystem.

responsibilities

• Implement EVM opcodes and subcomponents of the zkEVM circuits
• Optimize performance of the zkEVM circuits
• Coming up with and iterating on novel ideas to improve circuit performance
• Directly testing or creating developer tooling to ensure correctness of our circuits

requirements

• Strong background in math, cryptography, or related areas (most of the ZKP team holds PhDs, but no formal academic degree is required)
• Proficiency in Rust, C++, Golang, or Python. We work primarily in Rust, but prior experience with this language is not mandatory
• Strong problem-solving skills and interest in zero-knowledge proofs
• Prior experience with (physical) chip design, low level optimization of cryptographic code, or zero-knowledge proofs is a plus!

about us

Scroll is an EVM-equivalent zkRollup to scale Ethereum. Technically speaking, Scroll is built upon two major pieces. The core piece is the zkEVM, which is used to prove the correctness of EVM execution in Layer 2. We have been building it in the open with the Privacy and Scaling Explorations group at the Ethereum Foundation for over a year. But to turn the zkEVM into a full zkRollup on the Ethereum, we also need to build a complete L2 architecture around it.
